摘要：

Stop particles are expected to be the lightest squarks in supersymmetric theories and the search for these particles is an important experimental task. We therefore present the cross sections for the production processes p (p) over bar/pp --> (t) over tilde(1) (t) over tilde(1) and (t) over tilde(2) (t) over tilde(2) at Tevatron and LHC energies in next-to-leading order supersymmetric QCD. The corrections stabilize the theoretical predictions for the cross sections, and they are positive, thus raising the cross sections to values above the leading-order predictions. Mixed (t) over tilde(1) (t) over tilde(2)/(t) over tilde(1) (t) over tilde(2) pairs can only be generated in higher orders at strongly suppressed rates. (C) 1998 Elsevier Science B.V.
